Appnman ned 'February ze, laos. serial No. 302,969.

Tool'l whom it may concern: 1 Beit known that I, JOHN T. PORTER, a citizen of the v United States of America, residing at Pittsburg, in the I ,l county of Allegheny and State of Pennsylvania, have invented certain .new and useful lI-nproveincntsin` 'Iype-llVrit'ers, 'oi which the following is a specification,

reference being had therein to theA accompanying drawing.

This invention relates to certain new and useful imr rovements in tv )ewriters'V and the invention has for itsprimary object to dispense with the ll eyboard of a typewriter and provide a machine that can be'operated withone hand.

l E. My invention-aims to providea novel form of typet hand, Without necessitating the use of a persons sight Writerwhich canv be easily and quickly operated by one tov accomplish the same. In this connection, my invention laims to provide a machine Which can be `more'quickly operated than the present type of mayichineand with greater accuracy. To this end, the

'machine is constructed whereby a'lc'tter or manuscript can be Written With one hand and without the operators attention, otherwise than the manipulation of the machine by memory. In this manner, themachine`M permits of `a stenographer or operator following his or her notes with one hand, when a letter o1' manuscript is .j to be transcribed, While the 'machine is operated by the other hand. To accomplish this result, it isnecessary v 'that the arrangemcnt'oi the type used in connection with the machine be memorized, whereby the type lcan be shifted to print any desired character, numeral or punctuation mark. Instead oi operating the ma; chine by the fingers, as heretofore` I have devised a machine which will be entirely operated by a wrist movement thereby permitting of a greater amount oi work being accomplished 'upon a machine at one sittingjand with greater accuracy.

AAnothcrleature oi my improved machine `resides in the tact that l have'dispensed with the key-hoard, type l (arrying rods and'actuating levers and the other numerous appurtenances'generally used to actuate the 'typevoi an ordinary machine, such a'sthe Reming- 1.0117 or Smith Premier. Y c Theinvention in its broadest aspect involves numerous elements which are combined to produce a simple, compact and effective machine,` capable of .being i easily cleaned and free from all danger of being injured by constant use.` The elements as combined to produce an effective machine are abase'plate and frame, a carriage and platen, a carriage escapement and operating device, a ribbon shifting device and ribbon leed ing mechanism,v 'an automaticallyactuated carriage y] shifter, a type arm and cylinder and a cylinder actuating mechanism.

With the above and other objects in view, which will more readily appear Ias the natureol' the invention is struction and arrangement of the above mentioned elements which will be hereinafter more -fully described and claimed. i l

. In the accompanying drawings, I have illustrated the various elements, together with their appurtenant parts which are arranged to provide a quick acting and 'easily 'manipulated machine. -From the following description it will be noted that I have illustrated and used various little mechanisms and certain elements which are common to thev ordinary type of machine, such' as the Remington or ,Smith Premier. Thesel ele-v ments, namelyl a platen, guide rollers, and a manually operatedI platen mechanism are of a conventional form, and Ido-ndt care to confine myselfto the specific con! struction of these elements, as they may be slightly modified .to conform to the structural features of my l improved machine and to produce certain advantages In'describing'the various elements and their detail construction, each element will in its turn be -considered and then a general-operation set forth, whereby the machine may be fully understood by those skilled in the art 'of handling or manufacturing type writers.

The base-plate andframe.-Tl1e base and main frame of the typewriter consists of a substantially rectangular plate 1 supported by angle bars 2 arranged around the edgesoi the plate and secured thereto. The front edge o the plate at its corners is provided with upwardly extending standards 3, 3 and 4, to the upper ends of which is secured a transverse carriage supporting bar 5. The base plate 1in therear oi the standards 3 and 4 is provided with standards 6 and 7, carrying a Vtransverse carriage supporting bar 8,- similar Vto the bar 5. The confronting faces of rthese bars are provided with a plurality of horizontally alining pins 9 upon which are journaled rollers l0. Centrally oi the plate` l between the standards 3 and 4 and 6 and 7 is mounted A a yoke or bearing l1, the object oi which will be presently described.

At the rear corners of the plate 1 are erected stand-l ards 12, l2 inthe upper ends of which is journaled a type arm shaft 14. In iront of the standards l2, 12 and, centrally of the plate is mountedy a bearing 1.5 and an escapement supporting plate 16,. While intermediate said plate 16 and the yoke 11 is mounted a casing 17,

having alining'openings 18, 18 formed therein. Access is had to lthe casing 17 through the medium of an opening'19 formed in the base plate 1 beneath the casing.

Tite carriage and'platenr-A substantially rectangular -carriage frame 20, embodying end plates 21 and v22,

j and side plates 23 and 2'4, is slidably mounted upon the rollers 10. The side plates 23v and 24 are providedl with angle -supporting plates 25 and 26 respectively adapted tore'st' upon the upper edges of the plates 23 and 24 and assist in guiding and supporting the `carriage frame when moving upon the bars 5 and 8. Jour- -naledlongitudinally of the carriage frame is a platen' 27. One end o-the shaft 28 which carries the platen protrudes through the end plate 22 oi the carriage .rameand is provided with a pinion29, which meshes vwith a pinion 30 carried by the inner end of a shaft 31 journaled at one side oi the end plate 22 of the carriage frame. The shaft 31 extends through the end plate and is provided witha knob or hand wheel 32,' whereby 4it may be manually rotated to impart a rotary movemerit tothe platen 27. The opposite end of the shaft 28 within the end plate 21 of the carriage frame'is provided with a ratchet wheel 33, and adapted to engage said'ratchet wheel `are escapement dogs 34 and 35. The do 34 is pivotally mounted, as at 36, to the end plate -2 while the dog 35 is pivotally connected, as at 37, to a bell crank lever 38, pivotally mounted at thel rear edge ofthe end plate 21; The dogs' 34 and 35 are: connected'by springs 39, 39 to tle end of the :platen shaft 28 or may be connected to a pin carried by the end plate21'.' (See Fig. v22.) The dogs34 and 35 are employed for automatically rotating the platen 27, for

instance, when a line has been written and itis des ired to make a space, to write another line. The automatic operation of the dogs 34 and 35 willbe presently described, but reference will now be had to a Y lever 40 pivotallymounted as at 41,vv upon the front edge oi the end plate 21. The lever 40 is employed for manually rotating the platen at'any desired time and is provided with a spring held dog 43 which engages the' ratchet wheel 38 and is normally held in engagement therewith. By depressing the lever 40, the dog 43 is moved `,forward upon the ratchet wheel'33, and

when the lever is released, a spring 44 connected to the end plate 21 and the lever 40 is adapted to return the lever40 to its normal position, and through. the medium of the dog 43, partially rotate the platen. The manually operatedlever 40 and its appurtenant parts is oi a conventional form commonly used upon vtypewriter machines. i

rlhe side plates 23 and 24 of ythe carriage frame' 20 support a curved guide plate 45 employed for guiding a sheet of paper around the platen 27.

The depending ends of the end plates 21 and 22 support a longitudinally disposed rack 46,. which passes through the yoke l1 and meshes with a pinion 47 mounted upon an escapement shaft 48 journaled therein, said shaft .also being journaled in the bearing 15 and the casing 17 carried by the base plate 1. When a rotary movement is imparted to" the pinion 47 to move the carriage frame 20, the dogs 34 and 35 are actuated through the medium of a carriage stop 49 pivoted upon the side-plate 24 of the carriage'frame. The

carriage stop vconsists of two oppositely disposed cam arms 50 and 51, the cam arm 50 'being adapted to-engage in the end 52 of the bell crank 38, while the arm 51m-adapted to passth'rough'an opening formed in an angular guide plate 54, secured centrally of the trans-v verse bar 8. As the carriage frame 20 is returned to its normal position, at' the right of the machine, the cam arm 5l passing throughthe opening 53 of the guide -plate elevates the carriage stop and actuates the bell cranklever 38 to partially rotate the ratchet wheel 33 o the platen 27 The cawiage escapement and operating ldlrnitce.--The carriage escapement and operating device (see 'Figs- 16 to 20 inclusive) is carried by the escapement supporting-plate 16 of the base plate 1. It will be remembered that the shaft 48 jeurnaled in' the yoke 1l, casing 17 and bearing 15 is the main escapement shaft, and

the position of the bearing 15 relative to the Supporting lplate 16 necessitates the shaft- 48 extending through said plate. -Upon the shaft 48 adjacent to the supporting plate 16 is mounted a ratchet'wheel 55. Pivotally mounted upon the plate '16 adjacent to the ratchet wheeL'as at 56, is a curved lever 57 which extends upwardly over the 'shaft 48 and then downwardly and ,has its end extended outwardly, as at 58 'in order that an actuating rod 59 mayb`e pivotally connected thereto.

Pivotally connected to the lever 5 7, as at 60, is a pawl 61. The pawl is provided with a' laterally extending tooth 62 adapted to engage the yteeth of the vratchet wheel 55. The uppers edge of the p awl is providedl with'a slot 63 and a pierced lug-64. Connected to the pierced lug 64 and a similar lug .65 carried by the lever 57 is a spring 66 adapted to normally retain the pawl 61 in' engagement with the teeth ofthe ratchet wheel 55. Upon the plate 16 inthe rear of theratchetl wheel 55 is .pivotally mounted another pawl 67 carrying a tooth 68 and a rearwardly extending hook 69. The rearwardly extending Vhook 69 is adapted to extend over the upper edge of the plate 16 and is connected td a coiled spring 70 mounted upon the rear side of the plate 16. The coiled spring is employed to hold the tooth 68 in engagement with the ratchet wheel 55. The pawl 67 is provided with an opening 71, saidopening being formed by cutting or shearing the pawl and bending the material outwardly to vform a lug- 72, along side of the opening 71. The pawl v61 is mounted in' iront of the pawl 67, and extending through the slot63 of the pawl 61 and into the opening 71 of the pawl 67, isa longitudinally disposed lever 73, saidlever being pivotally mounted, as at 74 upon a post 75 carried by the base plate 1. The lever 73'e`xtends forwardly to the front' edge of the base plate 1 beneath the carriagev frame 20, and is provided withan operating handle 76. `A- slotted plate 77 is mounted to one 'side of the escapement device just described t9 receive the outer end of the lever 57 and limit yits upwardmovement.

In the'casing 17 is mounted aretracting spring 78, one end of which is connected to the casingl7 while the other end is connected to the shaft 48.` When the actuating rod 57 is depressed, and the ratchet wheel 55` rotated through the 'medium oi the `pawls 61 and 67, the spring 78 is wound up, whereby when the pawls 61 and 67 are released by the end of the lever 73, `the spring 78 will 4return the shaft 48 together with thel ratchet wheel 55 to their normal position.

When the actuating rod is being depressed, as will be presently described, the carriage frame 20 is travsling from the left side ofthe machineto the right-and the spring 78 is being wbundup. When the carriage has reached its limit and is automaticallyr released, the spring 78'is adapted to return the carriage to its normal position to the left of the m'achine. I i

Ribbon shifting deyt'cef-The end plates 21 and 22 of the carriage frame 20-are provided with depending brackets 79 and 80, (see Figs. 3 and 21). 1n the `brackets 79 and 80 are journaled shafts 81 and 82 respectively, andupon these shafts are mounted spools 83 and 84. One of the spools serves as a ribbon supply spool, while the other spool receives the ribbon. The strip of ribbon 85, which in/the present instance is wound upon both spools, passes over guide plates 86, 86 secured to the end plates 21 and 22 of the carriage frame 20.

Pivotally mounted near theA rear edge of the end plates 21, 21 are ribbon shifter arms 87, and between said arms are journaled rubber covered rollers 88 and 89, these rollers assisting in the guidance of aA piece of paperaround the platen 27. The arms extend rearwardly over the carriage :frame and are formed with upwardly extending portions 90 carrying outwardly extending pins 91'. Pivoted to the upwardly extending portions 90 of the arms 87 are hangers 92, 92. The lower ends oi the hangers 92, 92 are connected together by a transverse rod 98. i The forward ends of the ribbon shifting arms 87, `87 are provided with slotted lugs 94, 94, and' sliding in said lugs are ribbon shifting plates 95, 95. The rear ends oi these plates are pivotally con nected, as at 96-to plates 97, ,97, which in .turn are pivotally connected. as at 98, 9S to the hangers 92, 92.

placing a piece of paper around The ribbon shitting plates 95, (see Figs. 3 and 32) are cut and sheared, as at 99,99 and the material bentoutwardly to form guides 100 through which the ribbon 85 passes. By the arrangementof the ribbon shown in Fig-'21 of the dra'wings,it will be observed that the ribbon passes directly over the top of the platen, 27., and that the width ot the guide plates 86, 86 permit of the ribbon 85 being shifted through the medium of the plates 95, 95, hangers 92, 92 and the transverse rod 93; By pivotally mounting theribbon shifting arms 87, 87, which carries the shittingy plates 95, I am enabled to slightly elevate the forwardmost rubber roller 89, when g the platen, as shown in Fig. 3 of the drawings. vA sheet of paper is adapted to pass beneath the rubber roller 89, upwardly over and around the platen 27 and out under the rubber roller 89. The curved plate 45 supports the sheetof paper in passing over the edge of the bar 23 of the carriage frame, and beneath the roller 89,"it being observed that the'paper after being printed upon passes outwardly upon the same side of the carriage as it enters.

To actuate the roller shifting arms 87, 87 through; the medium of the transverse rod 23, I employ'a strap 101 consisting of two hinged yokes 102 and 103. rljhe yoke 103 is pivotally mounted as at 104 in brackets `105 car. ried by the base plate 1 adjacent to the casing 17 The pivoted end of the yoke 108 is provided with an outwardly extending lip 106, while the yoke 102 is pro-- vided witha hook-shaped member 107 adapted to engage over the transverse rod 93. The yoke 108 embraces the shaft 48, and extending downwardly through the yoke 102is an actuating arm V108 adapted to 'engage the lip 106. When the actuating arm 108 is depressed, as will hereinafter bev more fully'described, the' transverse rod 93 is moved forward through the medium of the strap 101 and the ribbon 85 is shifted at each change of the characters, that is, when small letters are being used' and a'shift isvmade to the capital letters, numer als or punctuation marks, 'as will hereinafter' appear.l

In order to return the ribbon shifting plates .95 to their normal position, springs 109, V109 are connected to the pins 91 of the arms 87 and to outwardly extending lugs 110 carried by the lower edges of the ribbon shifting plates 95, 95. y

Ribbon feeding mechanism- The ribbon shifting device just describedis employed for horizontally shifting the portion of ribbon 85 above the platen 27. ln order that the ribbon may be fed from one spool to an;` i

other, I have devised mechanism which is automatically actuated by the movement of the carriage frame 20. The forward sides` of `the dependingrbra'ckets 79 and 80 are provided with auxiliary I rackets 111, 111, and supported by said brackets is a transversely disposed guide bar 112. The ends ot' the shaftsl 81 and 82 extend through the auxiliary brackets and the ends of the guide bar 112,'and are providedwih ratchet wheels 118 and 114, the teeth oi the ratchet wheelfllB being the reverse of the ratchet wheel'l14. .Fulcrumed approximately central of the guide bar 112, as at 115, is a lever 116. Pivotally connected .to the upper end of the lever 116, as at .117, is a channel-shaped double acting paw] 118. Thechannel shaped ends of the pawl are adapted to overlie the ratchet wheels 113 and 114. Connected to a pin 119 carried by the lever l 16eme springs 120and 121, those springs beingconnerted to the pawl 118 ad- .jacent to its ends, wherebyiirst one end ot' thev pawl will be held in engagement with one of the ratchet wheels and then the other end of the pawl, withthe other of said ratchet wheels, as will be presently described.

turn the pawl to its normal position. The spring 120 in returning the pawl 118 to `its normal'pos'itiori actuates the ratchet wheel 114. Another spring 119a s mounted upon the pin 119, the ends 11.9b and 119c bearing upon the top of' the pawl 118. This spring is usedin Aconjunction with the springs 120 and 121, for maintaining the ends oi the pawl 118 in engagement with theratchet wheels 113 and 114. I

To reverse the movement of the ribbon 85 upon the spools, the arm 122 is adjusted to strike the pin 119, the `arm being swung downwardly to. engage the pin 119 each time the-carriage is shifted.v .1t will be seen that .when the pin 119 strikes the arm 122, the end 119b of the spring 119"L will force the end of the pawl 118 against.

' which it bears, into engagement with the ratchet wheel v.1114, while the end .of the spring .119 .will recede.`

When the arm 122 is adjusted to strike the pin 123, the

end\119 ofthe spring 119*L will force the pawl-118 downwardly to actuate the wheel 113, whilethe end 119b of the spring will recede. Y l

The automatically actuated carriage sh'ifter. -Upon the front carriage supporting bar is pivoted a locking lever 124 having notches 1 25 and 126 formed in its end. Also secured upon the carriage. supporting bar 5 is a guide plate orv bracket 127 having a slot 128 formed therein. Extending into the slot 128 is the'forward end of a longitudinally disposed lever 73, which has its opposite endv extending into the opening 71, and the slot 63 of the pawls 67 and 61 respectively. When` a letter or manuscript is being written, 'and the carriage is being moved from the right of the machine tothe lef-t thereof, thelever is maintained in a fixed position by the locking lever 124, the notch 125 of which engages the forward end of the' lever 73. This position of thelever 73- permits o 4the pawl 61 being actuated indee pendently of the lever 73, and the opening 71 of the pawl 67 is o ia sufficient sizeto permit of a'slight move? ment of sai-d pawl irrespective of the `lever' 73. The carriage frame together with -its attachment including the platen roller, the rack and the ribbon and its carrying mechanism, are movable upon the rollers 10 transversely of the frame, and is adapted to extend at the l ends beyond the frame so as to bring all partslof the paper into proper position beneath the type carrying roller. When the carriage framev 20has reached `the v limit of' its movement to the `flet, the dependingv bracket of the carriage frame 2O imping'es vupon the lever 73 and permits the locking lever 124 to descendv until the notch 126 engages the lever 73. The movement of the lever 73 .by-the carriage frame 20 moves the pawls 61 ,and'' out of engagement with the ratchet `wheel l55,Y permitting the retracting-spring 78 :carried within the casing 17 to rotate the shaft 48 and return the carriage frame 20 and its appurtenant parts to its normal position at the right ofthe machine. Upon the carriage frame receding, the springs 66 and 70 return the pawls 61 and 67 to their 'normal position, to 70 again be actuated by the rod 59. Type arm and cyl'imicni-Mounted centrally upon the type arm shaft 14 is a yoke or stirrup'129 having its rear ends connected together by a plate 130. The plate 13() is connected to the base plate 1 by a heavy 75 coiled spring'131. The `forward end of the-yoke or stirrup 12.9 is provided with an outwardly'extending arm-132.l One side of the stirrup or yoke 129 is proy vided with a short arm 133 to which is connected the actuating rod 59 employed or'actuating the carriage 80 escapement and operating device heretoore described. Detachably mounted upon the arm132 is a sleeve 134. Mounted upon the sleeve 134 adjacent to the stirrup or yoke 129 is a fixed sleeve 135, said sleeve beingsurrounded by a` coiled spring 136. The ends of the coiled spring 13 6 areattached centrallyof stirrups 137, said, stirrups being pivotally connected, as at 138, 138 to Acollars 139 and 140. The collars have their 'outer ende lcut away, as at 142, forming shoulders. .The collars.- l 139 and 140 are provided with openings .143 beneath Q0 the stirrups 137, whereby screws 144- may pass through the stirrups 137 and extend into the openings 143 to limit the movement of the stir-rups upon the' collars 139 and 140. Secured upon the sleeve 134 adjoining the collars 139 are stationary collars 145 and 146,.- The 95 stationary collars are vout away and provided with shoulders 147, 147 similar to the shoulders 142 of the collars 139 and 140, .but the collars 145 'and 146 are arranged the reverse-oi the collars 139 and 140 whereby -the shoulders of the adjoining collars .will'coniron't one .100

another. In cutting away the 'collars to form theirv respective shoulders, 1 cut away sufficient material to permit of a partial'rotation of the collars 139 and 140 in either direction, therotation of said collars onlybeing l limited by the shoulders 147 of the stationary collars 105 and 146. The result of thisconstruction is that -the sleeve 134 .can be turned to the right or to the left and the spring 136 will return the 'sleeve 134 to its original position.

Inclosing the spring .136 and the '145 and 146 is a cylindrical .casing 148, one end of which is flanged as at 150, and secured to the stirrup or yoke 129, as at v151, 151. "The cylindrical'casi'ng 148 carries a strap 152 'to which issecured a depending actuating arm 10,8.. f l115 Near the outer end of fthesleeve 134 is mounted'a collar 153 carrying a type 'cylinder 154 upon its forward end, andf a three-piece wheel'represented as a whole at 155 upon its opposite end. The central portion.1 56 ofthe wheel 155A has a portion of its periphery 120 provided withteeth 157 while the outer sides or pieces 158, 158 of the wheel 155 oim guide iianges at the ends of the teeth 157. "y

Upon vthe periphery o the ltype cylinder 154 are arrangedl the type 159 of my improved machine. The 125 .type are arranged in nine circumferentially arrangedyy., rows with nine-typeato each row, thus making eighty one type in all. .The forwardmost three rows of-type are capitals, which 1 term the first case ;the intermediate'threerows are small letters which vI ternathe 1 30 4seCOndcase, While the rearmst three rows are numerals and punctuation marks hereinafter referred to as Which my improved machine is manipulated. Intermediate the three-piece Wheel 155 and the end of the casing 148 is mounted a bracketll. Mounted between the brackets 160 and161 is a longitudinally disposed tube 162, said tube being slotted as at 163 and 164. In the tube 162 is mounted a sleeve lcontaining a coiled spring 166. The 4ends of the coiled spring 166 are secured to the ends of screws 167 and 16.8 thatV extend through the sleeve 165 andupwardly through the slots 163 and 164 of the tube'162. Upon the tube 162 is loosely mounted a casing 169, Which is slotted, as at 170, 170, to permit of the screws 167 and 168 extending therethrough. Secured upon the casing 169 adjacent' to the slots 17() thereof are slotted collars 171 and- 172', the screws 167 and 166 also extending into slots inl said collars. The collar 172 is provided with a depending eyelet shaped handle 173, the objectof which will presently appear. The rear end of the casing 169 is provided with a segment shaped rack 174 adapted to mesh with the toothed portion 156 of the .three-piece wheel 155 carried bythe collar 153 of the arm 132. The construction employed in connection with the cylinder actuating mechanism is somewhat similarv to the mechanism housed by the casing 148. The arrangement of the spring 166 Within the tube 162 permits of the casing being moved to the right or left by the handle 173,` and also permits of the casing 169 being moved longitudinally upon the tube 162 which through the medium of the segment shaped rack 174 and the Wheel 155, movesthe type cylinder upon the sleeve 134. By the arrangement oi the mechanism just described, I am enabled to shift the type cylinder 154 whereby any individual type 0i the cases can ben positioned in vertical alinement with the sleeve 134 and the typecylinder actuating mechanism.

By referring to Figs. 1 and 2, it will be observed that the type cylinder 154 is directly over the central portion -of the platen 27, and the ribbon S5, and When in this 'position7 the normal position of the type cylinder and arm is such that the i type is in position to be printed by depressing the arm 132, until the type cylinder is moved into engagement with the ribbon 85 of the carriage irarne 20. Should it be desired to print any of the-characters forward or in the rear oi the i type, the handle 173 is moved until the roW oi type containing the desired character is reached, this movement being permitted by the sleeve 134 sliding upon the arm 132, the movement of which is limited by the casing 148, and should the character be to the right or left of the i type, the handle 160 carried by the sleeve 134 is turned either to the right or left, as the case may be, to bring the required character in the required position relative to the platen. Thus the manipulation of the handle 173 longitudinally of the mechanism adjusts the cylinder 154 to bring the transverse row of charaetcrs which contains the required arms 87, 8 7 carrying the rubber rollers 88 and 89 are slightly'elevated to permit of the end of the paper character in proper position, and the manipulation of the handle 160 adjusts the cylinder to bring the longitudinal row of characters which contains the required character into proper position relative to the platen. The spring 136-is adapted to return the cylinder actuating mechanism to its normal position in vertical alinement with the arm 132 and the,v carriage frame 2 0, While the spring 166 is adapted toshift the type cylinder 154 toits normal position upon the sleeve 134, that is, so that the i "type will again be in position to he printed, this type representing the normal position of the type cylinder.

General operation-In inserting a piece of paper to be operated upon in the machine, the ribbon shifting being inserted between the roller 89 and the platen 27, and by either operating the lever 40 or the knob or wheel 32, the sheet of paper is passed around the platen 27 beneath the ribbon 85, and is thus disposed 8 5 'in position to be operated upon. The carriage frame 2O is .then shifted to place the desired portion of the sheetoi paper beneath the type arm 132. This arm is normally held in a partially elevated position by the spring 131 secured to the stirrup or yoke 129 and the base plate 1.

In order that the operationof my improved machi'ne may be readily understood, I will assume that an operator .who has memorized the-arrangement of the type 159 and is perfectly familiar with the manipulation oi the machine, is to Write the Word May" upon the paper within the machine. The operator grasps the bracket or handle 160, placing his or her.

fore finger in the eyeletshaped handle 173 oi the type cylinder actuating mechanism. As the first letter M is in the first case, the operator 'shifts the 'type cylinder rearwardly until the :61st row of type of the iirst case is disposed in printing position relative to the paper. As the letter M happens to be central oi the first row it is in position to'be printed. 105 ByA depressing the type arm 132, the M type strikes the ribbon and makes an impression upon 'the paper.-

As `the operator lightly grips the type armv 134, the' spring 131 Will return the type arm to its partially elevated position, and the spring 166 within the 110 l sleeve 165 of the tube 162 Will return the type cylin- 'der to its normal position, this being .accomplished through the medium of the segment shaped rack 174l and the Wheel 155, it being understood that the collar 153 is slidably mounted upon the sleeve 134. Simul- 115 taneous with the depression of the type arm 132 the actuating rod 59 movesfthe lever 57 carrying the pawl 61, and the tooth is adapted to recede over one of the teeth of the ratchet Wheel 55 until the type arm 132. is elevated by the spring 131. The upward movement oi the arrn132 causes the pawl 6l to rotate the ratchet Wheel 55, which through.the medium of the shaft 48l moves the carriage frame 20 a prescribed distance, or one space, and places the sheet of paper carriedby the platen 27 of the carriage' in position to receive an iI'n-l 125 pression of the next letter a of the Word May'." The ratchet Wheel 55 is' retained in its moved position by the paw] 67 and for future reference, I"desire to call attention to the fact that the rotation of the shaft 48 places the spring 76 under tension. lo print the next 130 manipulation of the arm .simply being accomplished 'by letter of the word May, which is a small a, the

operatonturns the bracket or handle 160 to the lelt thereby rotating the type cylinder 154 and placing the letter a in the position formerly occupied by the letter Vi. The type arm 132 is then depressed as be# fore to leave an impression of the letter a upon the sheet oi paper following the capital'l'etter M. To print the small letter y, it is necessary for the operator to shift the type cylindlfforwardly to the ior- Ward rowof the second case, which is accomplished by the handle 173.. lhehandlel 160 is then turned which places theletter ffy in the position formerly occupied-by the letter i'. l The type arm is then depressed as heretofore to impress the letter "y upon the piece o paper mounted in the carriage frame.

The partial rotation of the type arm tothe right/Oli left is limited by the shoulders 142, 142 and the shoulders 147, 147`oi the collars 139 and 146 respectively, while the longitudinal shifting of the type cylinder 154 is limited by the screws 167 and 168 moving in the slots of the tube 162, casing 169 and collars 171 and 172.

As the spring 1371 simply holds the type arm 132 in a partially elevated position, it is only necessary to iur# ther elevate the type arm to inake two or more spaces, such as would be necessary between-words and sentences After the type arm has been depressedfand recedes to its partially elevated position, the ratchet wheel 55 is only rotated one -tooth or space, but upon being further elevated, the ratchet wheel 55-can be further rotated,

either the distance of one or two'teeth, thus making one has-become accustomed to the movement of the type arm, 'said arm. can be easily .and quickly manipulated to make one space or two or more spaces as desired, this a vertical movement, while the printing osome of the typeis accomplished by partially rotating a portion 'of lthe type arm.

I'will-now assume that an entire line has been written upon the paper and `that* the carriage frame; 2O has almost reachedlits limit-of movement vto .the left of the machine.v As the bracket 8O strikes the lever 73, the lever releases the pawls (iliand and permits the spring 7 Br of the shaft 48 to return the carriage frame 20 to its normal position,vthis being accomplished through the :medium of the pinion 47 andllthe rack 46. Simultane ously withy this movement,`the carriage stopactuate's the dogs 34 and' 35 to partially rotate the'platen 27, to provide a space'upon the paper of the carriage, upon which another line may be written. The cam arms 50 and 51 engaging the guideplate 54 and the bell crank lever-38 actuates the dogs 34- and 35 to move the ratclnetv Wheel' offthe platen 27. f y

Should it be desired to return Vthe carriage frame -20- to its normal'position, at anytime, before acomplete line has been Written, the operator -moves the lever` 73 -vto release the pawlls .61 and .'67, thereby vpermitting the 'carriage to recede to the rightihand sid'e of-themachine.

To shift-the'ribbon 85 4laterally-over the J@laten 27,' while themachine is being used,A the ribbon shifting arms 87', 87' carrying-the ribbon shifting-'plated are ein,

each time the type arm 132 is depressed. 'lhe shifting',

`oi' the ribbon laterally over the platen is necessary in 118 to its normal position, in ordeif that it may be again y actuated. The springs serve to retain the outer ends of'the pawl in engagement with said Wheels yand the rotation of the wheel 113 is adapted to wind the` ribbon upon the spool 83 of the shaft 81, while the rotation teeth ofthe ratchet wheel 114. 4 It will be observed from the foregoingtaken'in: con'- nection Vwith the drawings, that I have devised certaini -novel mechanisms for automatically shifting' thecarl riage frame 20, shifting the ribbon of saidcarriage-and;

automatically rotating the platen-of said carriage, and;

4after a person has iamiliariz'ed themselves with the of the wheel 114 in the same direction asthe Wheel 1:13- f is prevented by the end of the pawl 118 engaging. the l manipulation of the type -ann 132, lit will be possibile to rapidly manipulate the entire machine.

It is obvious that the arrangement of the type 159v of the type cylinder 154 can be readily changed and rearranged lt0 suit the convenience of.' the owner or. operator of the machine, and in some instances, 'some of. the characters, numerals or pnnctuation'marks of the cylinder may be dispensed with, when the machine is employed fora specialv purpose.

-I do not care to Aconfine myself to the lspecificconstruction of my improved machine, as numerous'changes,` lsuch as are permissible by the appended claims, may be resorted to without departing from the spirit: and I '.105 .What l 'claim and desire to secure by Letters Patent,

scope of the invention.
